48=head1 NOTES
49
50Due to size concerns, C<EUC-TW> (Extended Unix Character), C<CCCII>
51(Chinese Character Code for Information Interchange), C<BIG5PLUS>
52(CMEX's Big5+) and C<BIG5EXT> (CMEX's Big5e) are distributed separately
53on CPAN, under the name L<Encode::HanExtra>. That module also contains
54extra China-based encodings.
55
56=head1 BUGS
57
58Since the original C<big5> encoding (1984) is not supported anywhere
59(glibc and DOS-based systems uses C<big5> to mean C<big5-eten>; Microsoft
60uses C<big5> to mean C<cp950>), a conscious decision was made to alias
61C<big5> to C<big5-eten>, which is the de facto superset of the original
62big5.
63
64The C<CNS11643> encoding files are not complete. For common C<CNS11643>
65manipulation, please use C<EUC-TW> in L<Encode::HanExtra>, which contains
66planes 1-7.
67
68The ASCII region (0x00-0x7f) is preserved for all encodings, even
69though this conflicts with mappings by the Unicode Consortium.
